The semi-translucent shells of these minuscule crustaceans make them nearly as transparent as the glass aquariums in which they are sometimes kept. In the wild, different species can be found in rivers and lakes throughout the world, including the central United States.

The animal is so clear in appearance that it only has color after it has eaten a colorful meal, which is typically plant-based and, therefore, usually green.
